Glyceraldehyde exists in two __________ forms.	enantiomeric
A monosaccharide whose ______ ________ _________ center ( the ________ carbon) has the same configuration as the D-(+)-glyceraldehyde is designated as a __________. Vice versa for the L-(-)-glyceraldehyde.	A monosaccharide whose highest numbered chirality center ( the penultimate carbon) has the same configuration as the D-(+)-glyceraldehyde is designated as a D-sugar. Vice versa for the L-(-)-glyceraldehyde.
The D and L nomenclature	Are like the (R) and (S) designations although they are not necessarily related to the optical rotations of sugars to which they are applied.
